IMPROVEMENT' IN -BOLTS FOR FLO-U'RING-MILLS.

'Thc schedule referred to in these Letters Patent and making partv of the same.4

To all uhomr it muy concerne.

Be it known that I, SOLOMON GODEREY, of Athe city and county of Peoria, in the State of Illinois, have invented 'a new and useful Improvement in Bolts for Flouring-Mills, of

which the following is a full,^clear, andcexact description, reference being had to the accompany'ing drawing which makes part ofthis' specification, and which represents a view'in' ged, owing'both to the glutinous natu-re of the vflour and thesticking: of the shives, or outer coating of the 'gra-in, in, the meshes of the cloth. The meal also passes from the bolts in a Warm state, and, consequently, must undergo a cooling process before packing, thereby causing extra labor, expense, and loss of time:

Now, it is -the object of my invention to pro vide means for keeping the bolting-cloth clear from obstructions, and at the same time, When necessary, cooling the meal in passing through the bolt; and to these ends my improvement consists, first, inapplying a blast of air to the exterior 'surface of a bolting-reel; second, in combining with a boltingree1 one or more perforated air-pipes so arranged as to discharge the air in jets upon .the exterior surface' of the cloth; third, in combining Witha bolt'- ing-reel a perforated air-tube capable of re` rolving on its axis so as to direct a current of `air upon the bolting-reel at any angle desired.

To carry out myinvention, which may readily beapplied to bolting-chests of ordinary construction, I arrange-inside the chest and near the reel oneor more cylindrical or tapering tubes of suitable size and material, either perforated continuously throughout their Whole length in the .form of a long slit, or at intervals in the form of tubes or short slots, as may be deemed most desirable, a current of air being forced through the pipes from a proper fan or pump.v

In the accompanying drawin g,which exemplifies one mode of carrying out the object of my invention, a bolting-reel, B, of any suitable 1 construction,

is shown as mounted in a chest .the reelrevolves,

or frame, A. An airtube,", in this instance of tapering form, is, mounted in the frame so as to turn on its axis, andis perforated with a series of holes, D, for the escape of theP air, which is forced in at the larger endof the tube from a suitable fan or pump, and impinges upon the outer surface of thev bolting-cloth as thus driving oi' thc shivcs and gummy (thus incidentally aiding the boltin g) and partly through the end vwith theoiial.

The air may be of any temperature desired, f

and when -itis lower than that of the flour, which comes vwarm from the stones, the ilour lWill be proportionately cooled.A If desired, it can be cooled sufficiently for packing without: 'passin g through the hopper-boy.

' The pipe E is .shown as constructed Witha slot,- G, extending continuously from one end to etheother, which is ofcourse amere modification of the other one, C.l By turning the tubes on `their axes the blast can be caused to strike thereel at a greater or less angle, as may be found most desirable.v The air-tubes may be made cylindrical, ifdesired, but prefer the tapering form, as'it insures amoreequa-ble distribution of the blast. Two or more pipes may be used, it' desired, and they may be applied on thel same or different sides of the reel. The details of construct-ion of p also be modified in various ways without departing from the spirit of my invention.

i What I claim as my invention, and desire States, is-L 1. Applying a blast of air to the exterior surface of a bolting-reeh substantially in the manner described, for the purpose of clean ing the bolting-cloth and cooling the iiour.

' 2. The combination, With a bo1 ti11greel,of one or more perforated air-pipes arranged to discharge lthe airin iets upon the external surfaceof the clot-h, substantially as described. 3. Thecombination, with the bolti1l1greel,of

vto secure by Letters Patent of thc -United one or more airpipes capable of turning on their axes to vary the angle at which the blast strikes the cloth, as set forth.

the bolt may matter sticking to the cloths. The blast escapes partly through the cloth on `the other sideof v the reel
